That is why I believe the second biggest decision Barack Obama has to make — the first is deciding the size of the stimulus — is whether to increase the federal gasoline tax or impose an economy-wide carbon tax. Best I can tell, the Obama team has no intention of doing either at this time. I understand why. Raising taxes in a recession is a no-no. But I’ve wracked my brain trying to think of ways to retool America around clean-power technologies without a price signal — i.e., a tax — and there are no effective ones. (Toughening energy-efficiency regulations alone won’t do it.) Without a higher gas tax or carbon tax, Obama will lack the leverage to drive critical pieces of his foreign and domestic agendas.

And he could make it painless: offset the gas tax by lowering payroll taxes, or phase it in over two years at 10 cents a month. But if Obama, like Bush, wills the ends and not the means — wills a green economy without the price signals needed to change consumer behavior and drive innovation — he will fail.

The two most important rules about energy innovation are: 1) Price matters — when prices go up people change their habits. 2) You need a systemic approach. It makes no sense for Congress to pump $13.4 billion into bailing out Detroit — and demand that the auto companies use this cash to make more fuel-efficient cars — and then do nothing to shape consumer behavior with a gas tax so more Americans will want to buy those cars. As long as gas is cheap, people will go out and buy used S.U.V.’s and Hummers.

There has to be a system that permanently changes consumer demand, which would permanently change what Detroit makes, which would attract more investment in battery technology to make electric cars, which would hugely help the expansion of the wind and solar industries — where the biggest drawback is the lack of batteries to store electrons when the wind isn’t blowing or the sun isn’t shining. A higher gas tax would drive all these systemic benefits.

A gasoline tax “is not just win-win; it’s win, win, win, win, win,” says the Johns Hopkins author and foreign policy specialist Michael Mandelbaum. “A gasoline tax would do more for American prosperity and strength than any other measure Obama could propose.”

An economics researcher at Washington University in St. Louis suggests that raising gasoline prices by $1 a gallon would reduce American obesity by 9 percent. Another study posits that if every American spent 30 minutes a day walking or cycling instead of driving, we would collectively cut carbon emissions by 64 million tons and shed more than three billion pounds of excess flab.

I couldn't agree more with this. If Obama wants to be the Green President, this is mandatory. You can tell the auto industry to raise fuel efficiency, but as long as gasoline is cheap, people will continue to buy gas guzzlers.
